stay with the basic exercises....i would recomend (in your case) only 2 Exercises in a 45 Minutes training, training 2 muscles groups in 1 workout, so itīs only 1 exercise for a certain muscle group.
for example
Chest & back
1. Bench-press, warm-up 4-5 Sets, do 2 heavy sets (3-6 reps), after 2 medium heavy (8-12 reps) + 1-2 high rep sets
2. Barbell rows, warm-up 4-5 sets, the same scheme like in bench press
You only have to warm up for 2 exercises which spend some time....but in these exercise you do 5-6 "working sets"
Biceps/triceps
Legs shoulders
i would also recomend to use for the next training cycle different basic exercises (like incline bench press, Pull-ups)
but i donīt know how often you can train 3,4,5,6 days a week ?
